Hi,
After solving the search and OAI problems:
There is a query that runs forever until the postgresql timeout is reached (12 hours in my case).
During this 12 hour period, several queries of these are executed on the server, causing a performance problem.
The first ones end up being solved in 1 hour, but the time goes up according to the quantity. Getting to the point of stopping the database.
The query:
2020-11-25 00:20:48 -03 [37312]: [1-1] user=revistas,db=revistas3 ERROR: canceling statement due to statement timeout

WHERE j.enabled = 1
AND j.journal_id = $8 AND (LOWER(asf0.setting_value) LIKE LOWER( $9))
GROUP BY names
) as t1 ON (t1.author_id = a.author_id)
ORDER BY author_family, author_given LIMIT 25 OFFSET 2650
Something can be done?
